IMPROVEMENT lN WAGON-WHEELS.

Specification forming part of Letters Patent No. 127,922, dated J one11, 1872.

To whom it may concern:

Be it known'that I, J DRAM PRIEST, of Detroit, in the county of Wayneand State of Michigan, have invented a new and useful Improvement inWagon-Wheels; and I do declare that the following is a true and accuratedescription thereof, reference being had to the accompanying drawing andto the letters of reference marked thereon and being a part of thisspecification, in which- Figure 1 is an elevation of the central portionof the wheel, with a hub-section removed, and showing the wood fillingin section. Fig. 2 is a longitudinal section of the hub and filling.Figs. 3 and 4 are perspective views of the'inner and outer hub-sections,respectively. Fig. 5 is a perspective view of the wooden filling of thehub; and Fig. 6 is a perspective view of the spoke.

Like letters indicate like parts in each figure. The nature of thisinvention relates to an improvement in the construction of that class ofwagon and carriage wheels which have sec-.

outer section of the hub, providedwith aflange,

b, at the inner end, which is concave on its face;

. the other end a forming the sand-band, which is frequently used onwooden hubs. B is the inner section of the hub, cast with asimilarlyconcaved flange, (1. Both flanges are pierced with bolt-holesc. G is the wooden filling, into which may be driven the metallic boxesin which the axles run. Around this filling is turned a recess, 6, whosewidth equals the breadth of the spoke-butt. The hub-sections are drivenonto the filling until the inner edges of their flanges are nearlycoincident with the shoulders of the recess, when the hub is ready toreceive the spokes D, whose sides are so shaped as to fill compactly theentire circle between the bottom of the recess in thefillin g to theperipheries of the flanges, while the eeges of the spokes are dovetailedto fill the space between the concave faces of the flanges after theyare driven up against them, where they are rigidly held by the bolts f,so that no spoke can be withdrawn until these bolts are loosened. Thespokes, having no shoulder or tenon at the butt, are obviously strongerthan any which has a portion cut away at the place of insertion in thehub, which should be the strongest to resist the stress at that point;hesides they are easier and more cheaply made, and more readily replacedwhen necessary, than a tenon spoke.

What I claim as my invention, and desire to secure by Letters Patent,is-- The combination of the concave-flanged sections A B of the fillingO and the spokes D, the several parts being constructed,arranged,secured together, substantially as described and shown.
